[Qgis-developer] R: Re: attributeMap()

[francescoboccacci at libero.it]

Hi Martin,
thanks for your answer. I receive another type of error:

"/home/francesco/.qgis//python/plugins/sextante_animove/href.py", line 126, in 
processAlgorithm
    idVar = inFeat[index]
KeyError: '0'

where is the problem?

Thanks

Francesco
